This can mean hard drive failure, corrupt mbr (master boot record) or possibly you left a cd/dvd in the rom. If you have your operating systems installation disk try doing a repair, not recovery console ---repair only first.
Before that go into bios and see if your hard drive is detected.
You can also open the case and feel if the hard drive is running. Maybe unplug it and plug all connections back into the hard drive, doing this with computer off!!!

You message cut out. It's very difficult if not impossible to wipe a hard drive when you're using that hard drive. You need to get a program like Gparted or Disk Manager. The first is free and can be downloaded.
